george soros doubles his bet on gold , page-30

Please correct me if I wrong but isn't there to ways to buy shares in SPDR Gold Trust,1st buy shares on market,2nd exchange physical gold for shares?.I find it interesting that the trust seems to be building on it physical gold position at the same time notable investors appear to be taking positions.May also be worth noting that anytime AUD gold price shows any strenght ASX:gold seems to build on its physical position as well.

Just more to ponder I guess.
